WebJul 30, 2024 · Major Enzymes. The process of DNA replication is catalyzed by a type of enzyme called DNA polymerase ( poly meaning many, mer meaning pieces, and – ase meaning enzyme; so an enzyme that attaches many pieces of DNA). During replication, the two DNA strands separate at multiple points along the length of the chromosome. WebRNA polymerase II (Pol II) bearings out transcription of both protein-coding and non-coding genes. Whereas Paul II initiation at protein-coding genes has been studying in more, Pol II initiation at non-coding genes, such as small nuclear RNA (snRNA) genes, is less well understood at the structural level. Here, we choose Pol II initiation at snRNA merkmal …
